1099 Contractor in North Carolina with a Hawaii Client: Where Do You File?
Answer
The client's location does not decide this. Self-employment income from personal services is sourced to where the work happens, so working from North Carolina keeps it North Carolina-source and North Carolina-taxed. Travel to Hawaii to work and that portion becomes Hawaii-source, needing a Hawaii nonresident return.

The client's location is the wrong thing to track. What matters is where you were sitting when you did the work — which is why a contractor's exposure to Hawaii is measured in days on the ground rather than in invoices sent.
Hawaii publishes no de minimis day count or dollar floor for nonresidents. Any Hawaii-source wage income above the state's general filing threshold requires a nonresident return, and that threshold is reset each year — check the current figure on the Hawaii Department of Taxation nonresident instructions before filing.

Questions people actually ask
I live in North Carolina and my client is in Hawaii. Do I have to file a Hawaii tax return?

Self-employment income from personal services is sourced to where the work happens, so working from North Carolina keeps it North Carolina-source and North Carolina-taxed. Travel to Hawaii to work and that portion becomes Hawaii-source, needing a Hawaii nonresident return.
Do reciprocity agreements help a 1099 contractor?
No. Every state reciprocity agreement in the country is an arrangement about wage withholding between two revenue departments, and a 1099 has no withholding to switch off. Whether North Carolina and Hawaii hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
